Given that my preference is to use Unix-style EOL for "text" files on
Windows, as every text editor I use (barring notepad!) understands LF
format, it seems to me that this proposal also means that the hook
would be optional for me. That suits me fine - I'd prefer to avoid
having hooks that are required for Python checkouts, as that means I
have to remember to configure them on each clone (IIUC).
Of course, this implies that your proposal only requires any action by
the user in the case of Windows users whose text editing tools insist
on CRLF format text files (sources, etc). Is that really a large group
of developers? (I honestly don't know).
I suspect that there is something missing from your proposal, as if
this were the case, then the problem appears to be limited to a very
small group of developers. Maybe it's Visual Studio that insists on
CRLF for source files? (I don't know, as I don't use the VS editor).
If that's the case, then maybe a VS hook would be an alternative
approach? (I can't imagine such a hook would be an *easier* approach,
I only mention it because it makes it clearer where the issue lies).
